Clive Drake, Sales and Marketing Director at Carisma Auto Design, said: "The Mercedes-Benz Viano conversion is our flagship model, as it is the ultimate in discreet luxury travel.

"Many of our clients are high-profile heads of states, celebrities or important business people, it is therefore not always possible for them to travel around in a conspicuous luxury limousine, however they still want the luxury and comfort that is provided by such a vehicle, this is where the Viano from Carisma comes in."
